Summary: On the 150th anniversary of the completion of the Transcontinental Railroad, Ali remembers the sacrifice of thousands of immigrant laborers from China through the work of a California artist. Jason Ma created the musical "Gold Mountain" based on the lives of those who completed the project, which shortened a perilous months-long journey to less than week, and transformed the American economy. Jason talks about how the musical has revived the memory of the enormous sacrifice made by the Chinese workers.
